In order to obtain hazelnut lines with the characteristics of strong cold re- sistance, large fruit and high quality capable of overwintering safely in Yanbian ar- eas, with 173 lines of Corylus heterophylla × C. heterophylla ×C. avellana hazelnut as materials, fruit-related characters were measured and analyzed. Eight excellent individuals were preliminarily selected for further identification of cold resistance and high yield. They selected single plants were 57-1, 57-3 and 55-24 of combination 6- 34-1×S1-5, 56-3, 56-5 and 55-19 of combination 6-34-1×S3-1, 21-12 of combination 6-37-2×S3-1 and 21-12 of combination 6-23-1×S3-1.
